I have a R9 270x on a Alienware X51 R2. It's a pure AMD card. Not from a manufacturer like ASUS or MSI. I tried every single driver since december. The 13.12 to 14.7 RC. No one works. When I use the default driver (VGA) of Windows, I have no problems. I even tried on OpenSuse, the problem persist. Some person seems to have a solution on MSI card. But what happen if you have a AMD branded card. Like others, the problem happen randomly. One day I can use ONE monitor, no game, no video, only Firefox and it works. At the moment I use TWO monitor, I have a black screen. If I play any game, I have a black screen.

Last chance... I there any CLEAR solution? My next step is to go for nVidia. Wake up AMD.

I had similar flickering and display stability problems with my Alienware 18. To solve it they replaced the primary GPU with another R9 M290X GPU. Since they have switched out both the R9's for HD 8970M's to resolve the problem of a black screen accompanied by 8 beeps, indicating an LCD failure.
